The operating temperature range for most SCSI drives, including this model, is 5 to 50 degrees C (41 to 122 F). A normal PC case should provide adequate cooling, however, if your enclosure is unable to maintain this range, we suggest that you contact your system manufacturer for information on cooling and ventilation hardware that is compatible with your specific configuration.
